1. The following should be always be observed
for safety
• Please report to or take consent by the supply authority before connection to the system.
• Be sure to read "THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR SAFETY" before installing
the air conditioner.
• Be sure to observe the cautions specified here as they include important items related to safety.
• The indications and meanings are as follows.
• After reading this manual, be sure to keep it together with the instruction manual in a handy place on the
customer's site.
Could lead to death, serious injury, etc.
Do not install it yourself (customer).
Perform the installation securely referring to the
installation manual.
Install the unit securely in a place which canbear the
weight ofthe unit.
Perform electrical work according tothe installation
manual andbe sure touse anexclusive circuit.
Attach the electrical part cover to the indoor unit andthe
service panel tothe outdoor unit securely.
Be sure touse the part provided orspecified parts for
theinstallation work.
Check that the refrigerant gas due not leak after
installation is completed.

• Incomplete installation could cause injury due to fire, electric shock, the
unit falling or a leakage of water. Consult the dealer from whom you
purchased theunitorspecialinstaller.
• Incomplete installation could cause a personal injury due to fire,
electric shock, the unit falling or a leakage of water.
• When installed in an insufficient strong place, the unit could fall
causing injured.
• Incomplete connecting and fixing could cause fire.
• If the capacity of the power circuit is insufficient or there is incomplete

• The use of defective parts could cause an injury or leakage of water
due to a fire, electric shock, the unit falling, etc.
• If gas leaks and accumulates in the area surrounding the unit, it could
cause an explosion.
• If there is a defect in the drainage/piping work, water could
drop from the unit and household goods could be wet and
damaged.
•Do not connect the ground wire to a gas pipe, water pipe arrester or

2) Indoor Unit Installation
The mounting wall should be strong and solid
enough to protect it from the vibration.
1. Mount the installation plate on the wall
with four Type "A" screws.
(if mounting the unit on the concrete wall,
consider using anchor bolts.)
• Always mount the Installation plate
horizontally by aligning the marking-off line
by means of the thread and a level.
2. Drill the piping hole with 70mm dia.
holecore drill.
• For right rear piping and left rear piping,
draw a line in the direction of the arrow
marked "D". The meeting point of the two
lines is the center of the hole.
• Drill the piping hole with a ø70mm hole
core drill. Drill the piping hole at either the
right or the left with the hole slightly slanted
to the outdoor side.

3. Piping and Drainage of Indoor Unit
1) Preperation of Pipings
1. Cut the pipes and the cable.
• Use the accessory piping kit or the pipes
purchased locally.
• Measure the distance between the indoor
and the outdoor unit.
• Cut the pipes a little longer than measured
distance.
• Cut the cable 1.5m longer than the length of
the pipe.
2. Remove burrs.
• Remove burrs from cut edges of pipes.
• Turn the pipe end toward down to avoid the
metal powder entering the pipe.
Caution:
If burrs are not removed, they may cause a gas
leakage.
3. Flaring the pipes.
• Insert the flare nuts, mounted on the
connection ports of both indoor and outdoor
unit, onto the copper pipes. Some gas may
leak, when the flare nuts are removed from
the indoor unit, as some gas is charged to
prevent the inside of the pipe from rusting.
• Fit the copper pipe end into the Bar of flare
tool about 0.5~1.0mm higher. (See
illustration)
• Flare the pipe ends.
4. Tape the flaring portion to protect it from
the dust or damages.
"A"
When properly flared, the internal surface of the
flare will evenly shine and be of even thickness.
After the flare part comes into contact with the
connectors, carefully check the flare finish.

2) Connection of Pipings
1. Remove the indoor tubing with Drain hose
from the hole
• Remove tubing holder and pull the tubing out
of the chassis.
2. Replace the tubing holder into original
position.
For right rear piping
3. Route the tubing and the drain hose
straight backwards.
4. Insert the connecting cable into the indoor
unit through the piping hole.
• Do not connect the cable to the indoor unit.
• Make a small loop with the cable for easy
connection later.
• Connecting cable
5. Tape the tubing, drain hose and the
connecting cable. Be sure that drain hose
locates at the lowest side of the bundle.
Locating at the upper side can be a reason
that drain water overflows drain pan inside
the unit.

CAUTION
After the confirmation of the above conditions, prepare the wiring as follows:
1) Never fail to have an individual power specialized for the air conditioner. As for the method of
wiring, be guided by the circuit diagram pasted on the inside of control box cover.
2) Provide a circuit breaker switch between power source and the unit.
3) The screw which fasten the wiring in the casing of electrical fittings are liable to come loose
from vibrations to which the unit is subjected during the course of transportation. Check them
and make sure that they are all tightly fastened. (If they are loose, it could give rise to
burn-out of the wires.)
4) Specification of power source.
5) Confirm that electrical capacity is sufficient.
6) See to that the starting voltage is maintained at more than 90 percent of the rated voltage
marked on the name plate.
7) Confirm that the cable thickness is as specified in the power sources specification.
(Particularly note the relation between cable length and thickness.)
8) Never fail to equip a leakage breaker where it is wet or moist.
9) The following troubles would be caused by voltage drop-down.
• Vibration of a magnetic switch, damage on the contact point there of, fuse breaking, disturbance to
the normal function of a overload protection device.
• Proper starting power is not given to the compressor.

for the unit operation.
6. Air Purging
1) Air purging
The air which contains moisture remaining in the
refrigeration cycle may cause a malfunction on
the compressor.
1. Remove the caps from the 2-way and 3-way
valves.
2. Remove the service-port cap from the
3-way valve.
3. Turn the valve stem of liquid side valve
counter-clockwise approx. 90 and hold it
there for ten seconds, then close it.
4. Check a gas-leakage of the connecting
portion of the pipings.
CAUTION: Do not leak the gas in the air
during air purging. Use vacuum
pump as far as possible.
18 ENGLISH
2) Checking a gas leakage
1. Connect the manifold gauge to the service port of 3-way valve.
Measure the pressure.
2. Keep it for 5-10 minutes.
Ensure if the pressure indicated on the gauge is as same as that of measured at first time.
NOTE:
The additional gas for air purping has been charged in the outdoor unit.
However, if the flare connections have not been done correctly and there gas leaks, a gas cylinder
and the charge set will be needed.
CAUTION : Do not leak the gas in the air during air purging. Use vacuum pump as far as
possible.
